The most expensive mistake involves using the agent’s recommended lawyer. The developer is paid when the deal closes, which is a different interest than looking after your interests. Separate legal representation costs a fraction of what is at stake and is the single best safeguard.
Putting your name to untranslated contracts ranks close behind. A sworn translation is inexpensive set against the sum being committed. Verbal assurances mean nothing if the written contract says otherwise — only the signed text matters.
Committing to an unbuilt project blindly has wrecked plenty of plans. Before paying anything, look at previous developments, the building permits, and whether payments are held in escrow. Late deliveries happen frequently even in good markets; abandoned sites are the exception but much more damaging.
Forgetting about resale is a subtler error. Any property for sale in brooklyn will one day be sold, and the pool of future buyers matters. A unit with no local demand takes longer to sell when sentiment turns.
Lastly, many buyers misjudge the ongoing obligations. Tax filings may be required regardless of whether the property in puglia earns anything, and california houses overlooked notices attract penalties nobody warns you about. Setting up a local tax adviser from the first year heads off the majority of these headaches.
